Marantz Professional MPM-3500R | Ribbon Microphone with Low-Mass Diaphragm and High Sound-Pressure Tolerance (XLR Out)

Low-mass ribbon diaphragm for the highest quality instrument recording
Dipole Polar Pattern (figure-eight) to be placed between instruments
Frequency Response: 20-20,000Hz ±3dB

The Marantz Professional MPM-3500R is a fine quality ribbon microphone to faithfully capture a complete sound picture—from the subtle nuances of stringed instruments to rock vocals and percussion.

The MPM-3500R’s low-mass ribbon pick-up diaphragm is specially designed to get to the bottom of the subtle details continuously missed by conventional microphones, yet it remains warm-sounding and natural for a particularly vibrant, lifelike recording. Meanwhile, and unlike many more-delicate ribbon microphones, the MPM-3500 is still effective up 135 decibels of sound pressure—the equivalent of an air raid siren. Note that it also utilizes 48 volts of phantom power.

The microphone’s dipole (figure-eight) pickup pattern enables it to be placed between instruments and capture both equally without picking up any off-axis noise in-between.

Superbly designed and crafted, the result is a durable microphone with high sensitivity, low noise and wide dynamic range unmatched by anything else in its price range.


Frequently Asked Questions


What is the good thing about a ribbon mic compared to condenser or dynamic microphones?

Ribbon microphones, by nature, are great at picking up fast transients. This makes them ideal for applications where tiny details are important, i.e. the pick of an acoustic guitar, the texture of a bow on a cello, or the attack on a percussive instrument. The ribbon is much smaller and more delicate than the capsules found in a condenser or dynamic microphone, which means it can be more sensitive to small changes and can respond faster. 

Their sensitivity can make ribbon microphones more delicate than their counterparts, so it’s important to not to drop the microphone or place it in front of an extra loud source (i.e guitar amp at eleven). A broken ribbon may result in distortion, crackling, or no sound at all!

Still, the MPM-3500R can handle up to 135 dB SPL, which is about the equivalent of a jet engine. So, don’t worry about using it to mic your drum kit or guitar amp at a listenable level. 


Do I need to use phantom power or a power supply?

Unlike most ribbon microphone, the MPM-3500R will require 48vDC power, either supplied by phantom power through the interface or mixer, or through an external phantom power supply. Check the specifications for your mixer or audio interface to find out if it can provide phantom power on its own, or if it is very important supply this through an external adapter.

Here is a simple procedure for connecting the microphone:

  1. Make sure that the gain or volume on your pre-amp, speakers and headphones are all turned down.
  2. Use an XLR cable and attach the female end securely to the MPM-3500R. Connect the male end to your microphone pre-amp or phantom power supply.
  3. Once the MPM-3500R is fully connected to the pre-amp, turn on the phantom power.

While disconnecting, at all times be sure to turn down your pre-amp, speakers, and headphones before turning off phantom power. Wait approximately 30 seconds after turning off phantom power to disconnect the MPM-3500R. This can help avoid damage to your equipment.

Important Note: Some ribbon microphones may be harmed by the presence of phantom power. If you are using an interface or mixer that sends phantom power on multiple channels at once, make sure that all other microphones connected may be able to receive phantom power before turning it on.


Can I use this microphone with my audio interface?

Your audio interface should be able to supply phantom power and have enough gain and headroom to adequately handle the sensitivity and dynamic range of the microphone. For recording quieter sources, an interface/pre-amp that can supply at least 50dB of gain would be ideal. This may not be necessary for louder sources like drums or guitar amps. Most, if not all audio interfaces available will be ok to use with this microphone.


What instruments can this mic record?

The warm, natural tone paired with the ability to handle high SPL’s make the mic ideal for loud but subtle instruments like brass or percussion instruments, though it can also excel with a variety dynamic vocals. Acoustic and stringed instruments like guitars, violins, cellos, etc. will also benefit from it’s clarity without making the instruments sound overly harsh, as may be evident with some condenser microphones. 

Keep in mind, ribbon microphones like the MPM-3500R are also subject to the proximity effect. This is a buildup of bass response as the microphone is placed closer to it’s source. Even as this may not be ideal for every situation, understanding this Even as positioning the mic can help lead to new and exciting ways to make the mic work for virtually any source.


How do I mount the microphone on to the stand?

The MPM-3500R comes with a custom shock mount for mounting to your microphone stand. It’s at all times recommended to mount the included shock mount first before attaching the microphone to prevent any accidental damage to the mic. Here is a simple procedure to follow:

  1. On your microphone stand, loosen the screw that holds the boom arm in place. This is the final arm where you are going to be attaching the microphone. After loosening the screw, this arm should be able to easily spin in place.
  2. Loosen the screw on the shock mount’s mounting piece and move the mounting piece up so that it is free to attach to the microphone stand.Note that the shock mount also has a mounting piece for the included pop-filter. Make sure to use the mounting piece that faces downward towards the bottom of the mount. 
  3. Hold the shock mount firmly in one hand and bring the mounting piece up to meet the threaded end of the arm on your microphone stand.
  4. Instead of spinning the shock mount, continue to hold it in one hand Even as using the other hand to spin the arm of the microphone stand, screwing it into the shock mount’s mounting piece.
  5. Once the shock mount is secured firmly to the microphone stand, position the shock mount for recording and tighten the screws on the shock mount and microphone stand so that they stay firmly in place.
  6. Place the microphone in its shock mount.
  7. While holding the microphone in one hand, gently spin the microphone mounting piece on the shock mount to secure the microphone in place.

Important: Always, make sure that the screws on the microphone, shock mount and stand are loosened before making any adjustments to their angle. Forcing any joint without properly loosening it’s screw can damage and strip the joint, affecting its ability to remain secure. The joints should also never be made too tight and should never require more pressure than can be provided by one hand. Again, this can damage the joint and affect its ability to remain secure someday.


Which side is the front?

The MPM-3500R is a side-address microphone, meaning the ribbon is parallel to its body. The microphone will accept sound from sources perpendicular to the microphone body, as opposed to a front-address microphone, like the Shure SM58, that accepts sound from its top or end.

When positioning the MPM-3500R, the front will be the side marked by the Marantz logo. Point this side towards your source for the best results.
